As an example of how wrong this law was, parents have been tried and convicted of child pornography for taking pictures of their children in the bathtub! What parent in America doesnt have multiple pics of their young children in the bathtub?
What parent doesnt have a picture of their naked 2 year old doing something 2 year olds do?
That's a red herring issue--this deals with kids involved in simulated sex. This is not justifiable, so you may as well stop trying.
